REFRIGERAT'ING ArPLrAuci'z.

Application filed February A11, 1924. Serial No. 692,002.'

To alli/)hom yt may concern'. v Be it known that I, FAY T. Routines, a ,"citizenh'ofthe United States, [residing at Memp `s, in the county of 'Shelby and State.

ot'rlen. essee, have invented certainnew and useful Improvements in Refrigerating Ap- *1 pliances, of whichthe following is a full, clear, and eXactflescr/iption'. such as will enable anyone ski red il fre art use the same.

v My invention relater'lto refrigerant con tainer ada ted for use in refrigerators, particularly ,t oseof the'ca-binet display type in which a portion of the interior of the re- '.15 frigerator, or refrigeration chamber, is used for holding goods which are to be kept cool,`

Aand the balance of the chamber is adapted to contain a refrigeratmg member or members,'which members are prefer-ably remov- -2`0 able and. 'disposed theends of thefchamber.

The object of my invention is to provide a'simple, inexpensive and eflicient refrigen ,ati member which will efectually promote-circulation of the lair into Contact with i va cooling medium and thereby thoroughly.

v comprisesv the novel features of construction hereinafter more fully set out in thedrawings, specification and claims.

In/the drawinvs: Fig. 1 is a vertical longitudinal section of a devic'econstrncted in accordance with my invention.

. Fig. `2 is a sectional plan of`the device zaken .on the lline II-II of Fig. 1.

Fig. 3 isa vertical section of the device o on the linevIII-III of Figs. 1 and 2 on-approximatelyf-'double the scale oli-Figs 1- and 2. Fig.v 4 is the container? or tank shown in Fig. 1, taken on the; line IV-LIV of Fig'. 3.

Referrhxg. now 4to the drawings in which t.) make and' an enlarged vertical section'ofthe Lvarious parts are referred to by numerals,v1 designates the casing of a refrigerator'of the cabinet type including the usual top 2,"bottom 8, ends 4, front 5' and back 6. The front 5 ispreferably formed with glass panels whereby the goods' disposed within the refrigeration chamber are displayed and' the back 6 is provided with doors 7 and 8 through which the refrigerant members and lthe goods yto be displayed within-the lcabinet maybe placed therein or removed there-l from, or through which access may be had to the interior of the refrigerator for cleaning or other purposes.

9 are brine trays adapted to receive the drip from the'refrigerant members 10. 11`

are drip pipes leading from the refrigerant tanks 10 and emptying into the brine trays 9 which drip pipes may be shut off by valves l2 when it is desired-.to remove the refrigerant tanks. 13 is a drip pipe into which the brine trays 9 discharge.

The refrigerant members 10 are preferably rectangular tanks of metal having bottoms 14, fronts 15, a back 16 and sides 17 and 18. 19-is a handle fastened to the back 16 to provide means for removing the tank for refilling. with a top 20 which lies thereover, but which The tank may be provided is not fastened thereto, or if desired, may I be left open.

l/Vithin each of these tanks are U shaped tubes each preferably of one piece construction, and each comprising an upper leg 21, a' lower leg;r 22 and vertical connecting leg 23. The upper and lower legs 21 and 22 have open ends which project through and are securely sealed to the side 17, the open end of the leg 21 being substantially vertically above the open end of the leg 22.

The leg 21 extends inward from the side 17 in a horizontal direction but inclined slightly downward therefrom, thence curves into the vertical 'section 23, which inturn curves outward into the Llower section 22 which inclines downward from the horizontal, and- -which extends from the vertical section 23 through the side 17 and terminates vas before stated in an open end.' The open ends `of these sections 21 and 22 being sealed to the side 17 by brazing or in Vsuch,othersuit- Y able manner as may be desired. The vbody of the U shaped tube including the vertical,

-seetion 23 thereof is entirely within the tank 410 and is spaced away from the side'` 18' so that a space is provided betweenmthe said' 4side 18 and the tube-which may be filled with ice and salt for refrigerating 'pur--` poses, and permitting the entire body ot' the tube to be surrounded by the refrigerating material. 24 are spacing members which secure the vertical leg 23 to the side 18 and hold it-properlyspaced therefrom. There may be one, two, or even more ot these U shaped tubes within tbe tank 10, preferably two only being used.

Immediately beneath the .lower end of each of the upper'legs 21 ot the `tubes is a short detlecting shelf 25 which direct-s the current of air toward the mouth of the tube. Thegeneral direction oi the circulation of air through these tubes is shown by the arrows von the drawing. The warmer airin the top of the refrigerator passes into the upper leg 2l and as it is cooled by the iee and salt' 26 becomes heavier and drops downward through the vertical sectipn and theniee outward through the .lower leg 22.

It will be especially noted that in this de.- vice I have provided a smooth and uninterrupted channel which isot the type best suited to take advantage ot' the slight dit'- 'ferenee in specific gravity caused b v the c0oling' o'l" the air within the refrigerant tank and that I thereby secure the maximum air circulation possible .in such a tank.

Having now fully deseribed my invention, what I claim and desire to seeure. by Trotters Patent, 'of the United States is: i

l. A refrigerant container7 com prising a tank having therein air-circulation tubes of ene-piece construction, each formed in subl stantially U shape. with curvilinear bends, the legs of the U being spread apart, and both ends 'of the tube being secured to the same side wall ot' the tank, in position .for the openings' in said ends to register with openings near the top and the bottom, respectively. ol" said wall. whereby air passing through the tube, from its upper to its lower end moves downward at all points in its travel, and a member securing each of the said bends in spa ed relation to the contiguous side wall f said tank.

2. A refrigerant container, comprising a tank having therein aireireulation tubes of curvilinear' eross-seetion, eaelr formed in substantially U shape. with curvilinear bends, the legs ot the U being spread apart, and both ends ot' the tube 'being secured to the same side wall of the tank. in position for the openings in said ends to register with openings near the top and the b0tt0m,. respectively, ot' said wallwhereby air pass-` ing'through.V the tube 'from its upper to its lower end nieves downward at' all points 1n its travel, andl an airuntake deiiector ad `iacent the upper end of each of said tubes.

In testimony whereof I have hereunto set my naine..
